The purpose of this standard is to clarify existing Code and City of Bellevue Fire Department (BFD) requirements for the design, installation and acceptance testing of smoke control systems. This information is to supplement existing code requirements and does not cover all aspects. This section applies to active and/or passive smoke control systems, and includes shaft pressurization as well as zoned smoke control systems. Questions or comments can be directed to the Assistant Fire Marshal- Plan Review. Design Approaches may include the Pressurization Method, Airflow Design Method, Exhaust Method, Passive Smoke Control and Performance Based Designs. All of these are defined in ICC standards. The objectives of such designs is to accomplish the following: (1) Contribute to the protection of life and to the reduction of property loss (2) Provide conditions outside the event zone that enable emergency response personnel to enter for rescue and fire-fighting operations (3) Maintain a tenable environment in smoke refuge areas and exit enclosures, and within the event zone when utilizing the exhaust method, for the required duration (4) Inhibit smoke from entering stairwells, smoke refuge areas, elevator shafts, or similar areas (5) Inhibit the migration of smoke from the event zone 11.01-2 Smoke control (when required).
